Hello Fast.I seen a few and if I rember right thay were 3 or 4" high.and thay make dogbones that do the same.Im hopping to hear back on a set I seen on line.Thay said that thay are 1 1/4 but the bottem can be made to fit 7/8s bar.Been 3 weeks and no news.would like to be able to mount them the same as the OEM.seen 4"riser with stright bars and that really looks nice,But looks kind of funny with ape hangers.
